Beyoncé became the first black female headliner of the Coachella music festival last year. Her live performance with drumlines, pyrotechnics, and more than 200 performers was jaw-dropping for Coachella attendees. Now it’s on Netflix as a concert film called “Homecoming,” which includes a lot of behind-the-scenes footage.
